In summary

PIE word
*prustós
From Middle English hore frost, horfrost [and other forms], from hor (“grey; greyish-white”, adjective) (from Old English hār (“grey”), ultimately from Proto-Indo-European *(s)ḱeh₃- (“darkness; shadow”)) + frost (“cold spell, freezing weather, frost; hoar-frost; rime”) (from Old English frost, forst, ultimately from Proto-Indo-European *prustós (“frost”)). The English word is analysable as hoar (“greyish-white; white”, adjective) + frost.
